Q
Can TSI Visitor Blocker block specific countries from accessing my WordPress site?
Yes. Enable ‘Country Blocking’ in the settings and enter ISO 3166-1 alpha-2 country codes (e.g., CN for China, RU for Russia, BR for Brazil) one per line. The plugin uses GeoIP lookup via ip-api.com to determine visitor location and blocks at the server level before WordPress renders content.
How do I block spam comments using email domains in WordPress?
Navigate to Settings > Visitor Blocker. In the ‘Blocked Domains’ field, enter email domains without @ symbols (e.g., spamdomain.com, tempmail.net). Enable ‘Comment Blocking’ checkbox. The plugin intercepts comments before they are saved, checking both the author email and comment content for blocked domains.
How do I "allowlist" or unblock someone who was blocked by mistake?
Access your wp-admin panel (blocking doesn’t affect admin access). Go to Settings > Visitor Blocker. Remove the specific IP, subnet, email, or domain from the relevant blocklist textarea. Save changes. For immediate relief, you can also add their IP to an ‘Allowed IPs’ section (if implemented) or temporarily disable the specific blocking module.
Can Advanced Visitor Blocker block IPv6 addresses and subnets?
Yes. The plugin supports both IPv4 and IPv6 addressing. Use CIDR notation for subnets (e.g., 192.168.1.0/24 for IPv4, 2001:db8::/32 for IPv6). The avb_ip_in_range() function uses inet_pton() for binary comparison, ensuring accurate matching across both protocols.
Does TSI Visitor Blocker work with caching plugins like WP Rocket or Cloudflare?
Yes, but configuration is required. Since the plugin executes on init, it runs before page caching. However, for Cloudflare or other reverse proxies, ensure the plugin checks HTTP_X_FORWARDED_FOR headers for real visitor IPs. Country blocking may conflict with Cloudflare’s own country blocking; disable one to avoid conflicts.
